Only one channel not starting up

The following .m3u link only shows the first image of the stream.

Channel is ALPHA GREECE and should work anywhere in Europe.

It works fine on the broadcaster's website and in VLC.

I have to manually restart the stream 3-4 times, and even then it's not smooth.

All other links work first time and VERY quickly, it's very impressive.

.m3u: #EXTINF:100 group-title="ΠΑΝΕΛΛΑΔΙΚΑ" tvg-name="Alpha Greece" tvg-logo="" channel-number="37",ALPHA HD
